The Web will continue to evolve regardless of what happens to Big Tech. Some Web 2.0 technologies are beneficial for the Web at large-- HTML5 greatly streamlined and simplified the language making it far easier to parse and understand for both human and computer, and pairing it with the power of CSS3 makes for an incredible duo. I like a good aesthetic, and that's why I haven't abandoned ameowli.dev for her Web 1.1 sister. It's not all bad out there.
Though, in your hypothetical world where Web 1.1 was the standard, then there wouldn't be a need for TFF or IWPPC because older browsers would be sufficient. You could probably even forgo LWK for bog standard Safari or even IE for Mac.
